Signal Recorder SR-7
My friend built this and I'm blown away with how much fun it is and the high level of polish. It renders 9 different strange attractors (Lorenz, Rössler, Aizawa, Chen, etc.) as particle systems — thousands of particles tracing chaotic paths in real time. You can rotate and zoom with touch/trackpad in 3D. The sound is the part that surprised me. It's not a soundtrack — the audio is generated from the motion itself using spatial audio, so tones shift as the attractor's behavior changes and the sound moves around you as you rotate the form. Put on headphones. The Playdate version uses the…

Voice recorder for iPhone, iPad, and Mac. Transcripts and summaries run on your device. Every recording exports as a markdown file — yours, on disk. The tools we use to capture shape how we think. A different pen changes the way you write; a recorder changes what you notice. In an age of AI, revisiting the proven practice of simply recording your thoughts turns out to be more relevant than ever. Signal Recorder SR-7 gives you a quiet space to capture ideas, conversations, and observations, then turns them into something you can search, skim, and build on. Everything runs on your device.

Echosnap AiNov 2025 · useechosnap.com · ▲62Hi everyone, I’m a solo developer and I’ve been working on a small tool called Echosnap AI. I built it because I often get ideas while I’m walking or doing something else, and speaking always felt like the fastest way to capture them. Echosnap lets you record a note and instantly get a clean transcript. It can also translate your recordings and help you stay organized with tags and folders. I tried to keep the app as simple and minimal as possible. This is my first time sharing something on HN, so any feedback or suggestions would mean a lot. Thanks for taking a moment to check it out.
Whisper Buddy2025 · whisperbuddy.com · ▲21I was laid off recently and, instead of looking for another job right away, I decided to build something I always wanted: a transcription tool that respects user privacy. Existing transcription tools often require internet connectivity, send your private audio to cloud servers, or lock you into monthly subscriptions. I wanted something different—so I built WhisperBuddy, a privacy-first AI transcription app that runs entirely on your machine. WhisperBuddy uses OpenAI’s Whisper model (see: https://github.com/openai/whisper). While the model may not always deliver the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

Homebrew 6.0.0▲1,481Today, I’m proud to announce Homebrew 6.0.0. The most significant changes since 5.1.0 are a new tap trust security mechanism, the new faster, smaller, default internal Homebrew JSON API, sandboxing on Linux, better defaults informed by our user survey, many brew bundle improvements, improved performance and initial support for macOS 27 (Golden Gate). Happy to discuss any questions here!

Hi HN! I was super frustrated at apps like tiktok and wechat preventing me from saving or downloading the animated gifs, so I made a little tool to turn a screen recording into a slack-sized emoji. Hope you get some value from this!
